Everything worked fine on Vista Home. Yesterday i downloaded Windows 7 Professional (original) from MSDNAAC and i have same problems with graphic adapter as some members here. When i go to Display properites it is showing me that i have Standard VGA Graphics Adapter and it is having only 14MB(like when someone installs any OS that does not have drivers in their own database). At first i try to download new drivers from NVIDIA for my graphic card that are supported for Windows 7. When I try to install them after the extraction of files and start of setup an error message appears "The NVIDIA Setup program could not locate any drivers that are compatible with your current hardware. Setup will now exit"
I am not rookie for computers and i tried to uninstall Display drivers, Windows uptade and similiar things and it wont help.
I will appreciate if someone can resolve my problem.

Hello
Recently i updated my laptop Sony Vaio VGN-FZ21M from windows vista home 32 to windows 7 ultimate 64. I didn't update teh OS, i just formatted and reisntalled it from bios. Now i can't find the right drivers for my Graphic Nvidia Geforce 8400M GT GPU.

What should i do? any suggestion? I was thinking to reinstall vista 32 and then update it to 7.. If i can't find them
Thanks in advice to all!

A:Problem Nvidia Geforce 8400M GT GPU

these are the latest 74 bit ones from Nvidia so they should work NVIDIA DRIVERS 285.62 WHQL

I have a HP Pavilion dv9934ca notebook with windows 7 and a Nvidia Geforce 8400m GS. Tonight the screen changed into a bunch of lines of different colors. I restarted and right before the login page it would go back to the screen with the colors. I went into safe mode and everything worked so i uninstalled my display adapter in the device manager and rebooted and windows worked but looks like crap. Windows then automatically downloaded and installed the update for the 8400m GS. So i rebooted and it went back to that colored screen. So I went back into safe mode and uninstalled the adapter again and downloaded the driver from Nvidias website and when I rebooted again i got the same screen. Does anyone have any idea what is going on? I'm starting to think the 8400m is toast.Thanks.

Hi delilah, Welcome to the forums ,try this link Drivers | drivers for mobile cards and laptops | laptopvideo2go.com , If you have any problems with the drivers try the Vista drivers in compatibility mode Compatibility Mode

I had to do something like that with my Compaq notebook (8200M graphics). Since doing that, I was able to get drivers from Windows Update or use the generic nVidia mobile drivers. I can't tell you whether it was necessary, but it may have helped.

I'm sure that this has come up many times. I recently purchased a new laptop and the card coming with it was the Geforce 8400-GS, not high-end but, on other forums said to be mid-range. It's supposed to play new games smoothly; just not at peak performance. The forum below categorized it as thus: The Mobile Graphics Card Info Page - Most GPU Qs answered - Notebook Forums and Laptop Discussion

Yet my Dell performance page rates me at a base score 2.6 in desktop graphics out of 5.9. Gaming graphics are apparently at a decent 4.1 out of 5.9 yet games and definitely PC game cutscenes do not run smoothly.
This computer even plays its default chess game at a noticibly choppy rate when it only demands a recommended 2.0 base score. I tried to run the 2003 game Jedi Academy and it runs though on it and other games the cutscenes are very choppy and gameplay has a very noticable FPS jumpiness. The newest game I played was a 2006 strategy game (Empire at War, I'm using the SW games for testing because they tend not to be very demanding) and it also played choppy.
These games don't demand very much and Jedi Academy is honestly pretty ancient. There are no viruses or bugs on the computer nor is it bogged down with programs. Lastly running videos is often difficult on or off the internet. Many times the frame rate on these is reduced. The graphics card is adjusted to the medi... Read more

Hello,I just installed Windows 7 today. When I booted up the computer, to my surprise aero peek did not load because it says that my video card does not support it. When I went to check what video card was being detected, the 8400m was not showing up. I downloaded the drivers for windows 7 off of the nvidia website and still no go. I am using a Dell XPS with 4 gigs of memory and a 2ghz Dualcore processor.

What version of windows are you running? Their are alot of threads about the 8400M. I'm kind of tired so if you'll use the search function at the top of the page and just enter drivers 8400m or nvidia 8400m you should get several threads that have delt with this issue. Sorry I can't walk you through it but it's 1:36 Am right now and I'm tired. Also when you have the time please go to your user CP top of page and fill in all of your system specs as it will help others help you if needed in the future. Thanks and welcome to seven forums.

Greetings to everyone out there, I am new to the forum. Feel free to critique me if I do or say something wrong.

I purchases a Dell 1300 XPS around November, also u should know I keep very good care of my Laptop.

Recently (being the last month) my computer has been freezing (at least the screen) it flickers green and red, then it pixellates, then my computer crashes.

However about two weeks ago my computer flickered and pixellated, but didn't crash. My computer reinitialized my graphics card and started working. It then told me my graphics card had failed. This was great for me because up until then I really had no idea what was going wrong.

So I now know what my problem is.

Then I decided to go onto cyberspace and look around to see if anyone else had the same problem. I found, Yes! Few people did. However no one has been able to solve the problem.

I've updated my driver, rolled back my driver and have come across nothing but failure. The only thing that I've found to work is just disabling my graphics card, which is pretty lame because my computer goes into fits whenever I try to play a movie or a game.

Please if anyone has any information that would help me it would be much appreciated.

Hello and welcome whome mate some specs would be good - run this Speccy - Download and send some info on them.

But first have a look at this Code 43: Windows has stopped this device because it has reported problems

I have had a couple of taskbar messages now to tell me the GPU has crashed and fixed itself, previously i had thought it was because i was running 3D games in a window, the problem shows itself as random colour blocks on the desktop and then the whole display flashing, like the computer is about to go into a UAC prompt, culminating with the message on the taskbar regarding the GPU. but now it is happening just with DreamScene running, so im all excited 'cause woo hoo, fiinally Vista is doing something other than just working right anytime all the time. I am using Vista Ultimate with SP1 32bit on my dv6519tx laptop, the laptop had Vista home premium originally, and I have the latest Nvidia driver from HP which is driver 7.15.11.7432. I have downloaded the latest Nvidia driver from their website, but as this isnt specifically a mobile 'M' driver, i havent yet installed it. Has this happened to anyone else?

A:Geforce 8400M GS driver problems

well using an nVision modded inf i installed driver version 7.15.11.7637, will see if this makes things more stable.

After upgrading a Dell Inspiron 1420 to Wdws 7 Home Premium from Vista, the screen either goes blank or freezes. After updating the Nvidia GeForce 8400M GS driver (195.62 WHQL 12/04/09), I now get a BSOD when it crashes. All other drivers appear to be updated.

Rebooting after a crash usually causes either a split screen with 2 desktops or 1 low-resolution desktop. Reinstalling Wdws 7 only lasted an hour before the problem started again. Using a prior Restore Point gets it going again but only briefly.

The problem appears to be the Nvida video driver that stops working for some reason. Attached is the Minidump zip file and System Data files.

Thanks for your help.

I noticed an old thread around and found it because i experienced the same issue with my nvidia card an i have tried it with a couple models different from 8400M GT and this solution worked just fine.

At a point my graphics card went berserk and from that moment on i had some vertical blue lines over the entire display.

At first I thought it was a OS related issue but after i kept reading and browsing around i noticed that most people recommended to contact Vaio support and they should work out the issue for free in about 3-5 days.

Another solution would have been to bake the entire motherboard which to be honest, i didn't really have the guts to do it

I just wanted to let you all know that this solution really worked and my Vaio has been dunning just fine for the past 4 months without any issues as well as a couple of 2 other machines i applyed this solution to.

1. Buy thermal paste2. Take your machine apart ( only the case until you can actually reach the video card)3. Take a hair dryer and hold it at 3cm above your card and turn it on4. Keep it running for about 2:30 - 3 minutes5. Make yourself a tee or a cofee and let everything cool off (this is very important because when you apply the thermal paste it is cooler and you could crack something)6. Apply thermal paste over the video card chip7. Reasamble your machine

After this everything should run perfectly

A:NVIDIA GeForce 8400M GT PROBELM

Hello andreyg13 and welcome to the forums

Thanks for sharing your solution with us I'm sure others who are experiencing this problem will really appreciate your efforts!

I have a Dell Inspiron 1420 that was misbehaving; on start-up, the monitor appeared "dazzled". Disabling the GeForce 8400M GS allows it to start and function with what I assume is the less-capable but at least functional built-in video. I believe that the GeForce chipset has failed and I'm thinking of replacing the motherboard, which I understand is the only way to cope with the failed GeForce video "card".

How can I verify my diagnosis? I ran the Dell diagnostics from their site, but with this device disabled I don't think it gets tested. I'd like to know for sure that this is the only way to proceed before I buy a new mobo.

I ran System Recovery and Start-up Repair multiple times from the hard drive and from the Win 7 DVD. I've installed the newest GeForce drivers and rolled the driver back to a version from September, 2013, with the same result. These steps have persuaded me the problem is in the HW, but I'd appreciate some reassurance. Maybe I'm putting too much into the reports about the GeForce chip problems and lawsuit for 1420 owners (too late for me).

If I do replace the mobo, I'm inclined to buy one that uses the Intel video chipset instead of the GeForce...to preclude the same problem. Or am I just trading a known GeForce problem for Intel problems that may be worse?

So, I have upgraded my laptop from Vista-32bits to Windows 7-32bits. I often play games and once my graphics card failed and made my laptop restart. In my attempt to fix it I think I only made it worse by messing up in the device manager, it seems I deleted my graphics card to try and reinstall it. Now I don't seem to be able to re-add it to my device manager, I've tried to download the driver but it does't seem to work, I am now using the Standard VGA dislpay. I have a Sony Vaio VGN-NR21S. What can I do to get it back to work, is it a hardware problem or a driver problem? Thanks in advance.

The older Vista drivers should work, if not, try to run them in compatibility mode. Let us know how you get on.

I've been looking for the last while for a laptop and graphics is one of my main concerns. Before I start, I want to make it clear that I'm not looking for really high graphics quality because I'm limited by budget, and on laptop you can't upgrade above the two mentioned cards.

So basically I had been thinking about getting a Dell Vostro 1510 with Geforce 8400m GS, but just recently saw the Dell studio 15 with ATI Radeon HD 3450. It would cost me about £65 more to get studio atm, but will also get extra 90Gb Hard disk space, and a 2.1 GHz core2duo over the vostros 1.83 GHz.

In terms of performance, I basically want to know, is the Radeon better than the 8400? Im not looking to play the newest games like crysis etc but do want to play some like call of duty 4, which i know works on the 8400.

This is my first post so please bear with me. I have a Dell XPS M1530 running windows 7 build 7100 32 bit. I am having problems with installing the correct driver with my Nvidia Geforce 8400M GS graphics card. I can currently only use the standard VGA graphics adapter or else my computer will not even start-up properly, Freezes at starting windows screen. I have tried installing the forceware drivers and have also visited NVISION.I would just like to know if there is any specific driver that i need based on my computer type.

Someone please help me, I'm so confused I see all these sights with info and instructions and so much of it is old or been removed. I need someone to please point me in the right direction as far as getting a driver to correctly run my card. I use the HDMI out exclusively on this laptop and need my card to work. Someone out there please help!

My HP dv6735en with above graphics cards just vanished after upgrading from vista to win 7. In device manager the only listing under graphics is the VGA card (even screen saver shows insufficient graphics error) I tried searching new hardware no luck

A:Nividia GeForce 8400m gs just vanished after win 7 upgrade

Sound like you need to install the graphic drivers. I'm a little surprised that the Vista drivers didn't carry over, if you did an in-place upgrade to Windows 7. (Or did you do a clean install?)

Because notebook makers tend to use custom device IDs for their graphics adapters, the place to begin is with the manufactuer.

HP doesn't list Win7 drivers for that notebook, but you may be able to use the Vista drivers:

I just installed Windows 7 onto my Vaio Laptop AR630E. Windows 7 is not recognizing my video card (NVidia 8400M GT) at all. I can't find it in the device manager nor can I download new drivers for it. The Sony website has no new drivers for my notebook's model.

I tried to download from NVidia's website but it could not locate my video card either.

This is for Torrentg. Can you please create a custom Inf file for me. I tried everything incl downloading the latest Nvidia driver and mMobilityModder to no avail. I am running windows 7 home premium 64 bit on a sony Vaio laptop with Nvidia geforce 8400M GS and below is the info you need on my video card:

I've recently been having trouble installing official and forceware drivers for my Geforce 8400m GS on my Dell 1420 since I upgrade to Windows 7 32-bit from Vista. When I uninstall my current drivers and reboot Windows fails to boot in normal or safe mode. Generally when I install drivers I reboot into safe mode, run driver sweeper and properly install them. Windows kept freezing at the classpnp.sys file so I changed the file to classpnp.old after some research but it started to BSOD me at the disk.sys file.

So I tried to just outright install the drivers from device manager by upgrading and I would get a message saying Windows couldn't find drivers compatible with any of my hardware. I've done a lot of homework, downloaded countless drivers, disabled aero, used mobility modder, and done just about all I feel I can do to fix this. These drivers worked fine with Vista and I really don't want to downgrade because I lost my product key and disc so that would be a pain. If anyone has had this issue and knows of a driver of modified inf file that would fix this problem I would greatly appreciate it. This has been frustrating to say the least

Hello chribroo, Welcome to Seven Forums. You'll have to bear with us, because we'll likely advise things you may have tried, but if we don't, we won't know we are missing the answer. One of our members, FZ21Z, has a nice little tute here, followed by discussion, on our forum that could be a good start:

NVIDA Driver Install - Start To Finish...

It's also been suggested you download the Vista driver from your manufacturers website. As I said you may have been there, done that, but we will not know for sure until we ask. A Guy

I am trying to sort a lappy out for a friend and it is driving me crazy, not having any joy over at Nvidia or HP so hopefully you good folk can help. I have read a lot of posts here and over at nvidia and have tried most of them but to no avail.

No matter which driver I install, even using Mobility Modder, the result is the same ....black screen after windows logo upon restart, so all I can use is standard vga adapter.

Tried also downloading the driver and then manually installing via device manager and noticed i have 3 instances of my card, could this be the problem? If so how would I correct it.

Any other help would be much appreciated.

Hello...I have Vista on my laptop, and when I first checked, I had a [Nvidia GeForce8400M GT] Graphics Card... I have done nothing wrong, and windows have changed it to a Standard VGA Graphics Adapter.I installed a piece of software (after the incident) and that discovered what my graphics adapter/card was... Why can't Windows.. I have ran DXDiag and all solutions like that... Is there anywhere to download a [Nvidia GeForce 8400M GT] for VISTA - Vista Only... Or a solution???

A:Nvidia GeForce 8400M GT... VISTA HELP REQUIRED!

Hello Joeyc2410,

Have you tried to automatically update the driver using "Update Driver Software" in the Device Manager? or tried downloading the latest driver from the nVIDIA website?

You could give Forceware drivers a bash if you're really struggling, but there really shouldn't be a need.

I have had to recently reinstall Windows Vista onto my laptop. In the Device Manager\Display Adapters all it says is 'Standard VGA Graphics Adapter' I know for a fact that my video card is Nvidia GeForce 8400M GS TurboCache, but when I install the driver for this I get a BSOD error. I tried the automatic search on nvidia.com/drivers and installed the driver that came up, the same happened. Is there a way to have Windows recognize my video card as the one stated above?

I just installed windows 7 professional last night and when trying to personalize my theme, i realized that i couldn't change window color. It only gave me the contrast themes unlike in vista where i could choose the color and it would still look like vista. I'm not sure if that last sentence made much sense, but i hope you get the idea. I can still use the desktop backgrounds and sounds, but not the aero window colors.

When I go to device manager, the only graphics adaptor it shows is the standard VGA. When I had Vista I didn't have any problem. But now that I have Windows 7, the OS won't detect the graphics card. Is it not compatible with Windows 7? I saw another post with a fix for the 8400M GT, and was wondering if maybe there was hope for me.

I hav sony vaio vgn-fz11z laptop with Windows Vista Ultimate 32bit and NVIDIA GeForce 8400M GT graphics card. It went black while playing a game. I restarted but it showed black screen with dotted vertical lines and freezed. I restore it in safe mood. It did not show GeForce 8400M GT graphic card but just Standard VGA Graphics Adopter instead. I tried to reinstall drivers (sony vaio orignal) but on restart,it again freezed.

Then i reinstalled fresh vista 32bit. But its just showing standard VGA adopter card. when I Tried to update it with the driver for NVIDIA GeForce 8400M GT graphics card. it refuses saying that driver is up to date. Then i just run the setup file for the driver, it got installed and also shed in device manager as GeForce 8400M GT, but on restart it again hung with black screen with vertical dotted lines. Now i rolled it back to standard adopter VGA card and system boots. System also show vertical white bands as in figure while running or adopter card as shown below.

Recently I've had my Sony Vaio crash on me, not the O.S. but the graphics card. At power on, the VAIO logo would have colorful line running threw it. Well I found a temporary fix for this problem. YouTube - Sony Vaio VGN-Ar520E Graphics card repair. . Me fixing this problem, If you have any questions. Please feel free to E-mail me.

I recently had problems with the factory installed Vista 32bit on my Sony Vaio VGN-AR51E.

I decided to install Windows 7 64bit and since then my laptop has not found my graphics card Nvidia GeForce 8400M GT.

On device manager, display adapters are shown only as Standard VGA Graphics Adapter but on Vista my graphics card was also shown.

I have tried downloading all relevant drivers etc but the Nvidia installer says no graphics hardware can be found.

I am half decent with computers but have no idea when it comes to editing the .nfi (or whatever its called) files that I have seen other posters suggest.

Can someone please confirm if my card is even compatible with my OS and what is the best route to take.

Also, I only found out that my graphics card was not in use whilst trying to play Rome Total War, and the game would not start as it said DirectX 9 is not installed (I am currently using DirectX 11). I have tried all the downloads for DirectX 9 with no avail so im focusing on the graphics card issue.

Other games, such as SimCity 4, work fine with the standard vga graphics adapter though.

For any more info required, just ask.

Much appreciated

A:Nvidia GeForce 8400M GT not found after Windows 7 64bit install

The 8400M GT is currently being driven by the generic Microsoft driver.

Is this the driver you tried? http://us.download.nvidia.com/Window...ional-whql.exe

Here's the full text of the address to the driver minus the "http://" so that it's not automatically 'linked' and automatically truncated: us.download.nvidia.com/Windows/314.22/314.22-notebook-win8-win7-64bit-international-whql.exe

I've been running Windows 7 after upgrading from Vista for a couple of months without any problems. The compatibility program keeps giving me the all clear, but for the past week my graphics card has been spontaneously crashing when I go to play Minecraft and Bejeweled 3. The first two times it recovered and I couldn't seem to track down an error report to find out why; tonight when I opened up Bejeweled I had to manually shut the laptop down as the screen glitched and froze (the image started to break up into bars and then locked completely). It's now crashed twice in one night on games I seemed to be able to run previously without much issue (well, minecraft is its own monster, but Bejeweled has never done this to me before! ). I've been surfing the forums and it looks like there have been very similar issues with the card and Windows 7, but all the related posts are well over a year old and don't quite seem to match up. I'm creating a backup and am prepared to try and update the driver as one old thread suggested, but I wanted to get some current feedback first.

- If anyone has recently had this model of card crash on them, did a driver update fix the problem? (I ask because a similar old thread said the update seemed to make it worse, but that user was having some other symptoms ... Read more

A:INVIDIA GeForce 8400M GS card crashing, some Qs b4 I update driver?

While a driver update might work, I don't think this is the real cause of the problem...it sounds like a hardware failure to me, most likely due to overheating. Does the card have a fan, if so, can you open up your machine and check that the fan is still running?

Doh, just noticed it's a laptop (mobile chipset). You could use monitoring tools such as SpeedFan or one of my favorite Windows sidebar gadgets called GPU Observer to check the temperature.

Anyway, the driver you're looking at is the correct one and it's not a bad idea to update - just be on the safe side and make a backup or restore point first.

The game loads fine until i begin playing, and the graphics are completely messed up. Picture attached below in thumbnails

I can still move around in the game but cannot play it as you can see. What happened first was I had an issue with direct x 9.0. I would play the game and it would crash within couple hours of playing and it would give me this error "Directx Has Encountered an Unrecoverable Error" which i already know I have the most recent update for that. Checked my DirectX files; No problems found there and i have the most recent DirectX update. Checked my Graphics Card to see if it needed to be updated. Looked as though it did so I updated it to the most recent update for the Geforce 8400M GS: Verde Driver v266.58. After that I had no more crashes and no more Directx errors but, I started having the graphical issue problems in the picture. I have also made sure I have my settings set to the lowest settings in gameplay because my video card is not that impressive. It's beyond me at this point what to do, I have uninstalled all my graphic drivers and re-installed them again to still come to this problem. I bought the Modern Warfare 2 game from steam, and I know all my specs meet minimum required specs besides my CPU speed, but i still don't see why I shouldn't be able to play the game. I will post more information on here including the DxDiag Report.
